Ring Size Guide

At D. J. Massey & Son we know that when it comes to buying a ring, getting the perfect size is important, but not always easy! Particularly if you are planning on surprising your partner, getting the right size can be a tricky business.

Of course, the ideal way to make sure you get the right size is to visit us in-store and let us measure you for your ring size, but we know that this is not always possible. Below is a table showing UK Ring Sizes and corresponding inside circumference measurements (please note in some cases half sizes may be available, contact us for more details)

To measure your ring size using circumference, download our handy Ring Sizer tool.

Helpful notes:

  • The thicker the band of a ring, the tighter the fit will be, so if you are choosing a ring with a deeper band it’s best to size up.
  • It’s best to measure your ring size in the evening when your fingers will be at their largest. It is advisable to not measure your finger when it is cold as they will be smaller than usual.
  • Please remember that the above guides are an estimate only and the best way to ensure a perfect fit is to be professionally measured. You can visit us in our showroom anytime and we will be happy to do this for you.
  • If you are planning a surprise proposal, the easiest way to get the right ring size will be to measure against an existing ring. Of course, your partner is unlikely to wear rings on the third finger of their left hand! So you can always use a ring worn on the index finger and size down slightly.
  • If you’re at all unsure about ring size, the best choice would be to go for a larger rather than smaller size. A ring that just won’t go on your partner’s finger may ruin the romance somewhat! A little too big is a problem that is easily resolved.
